The rush to add displays to devices which previously did not have them, such as universal remotes and data-storage hubs, is raising concerns about whether screen manufacturers can keep pace with demand. Anecdotal evidence suggests the emergence of screens on more devices, especially smaller ones, is straining supplies already under pressure by the surge in demand in 2007 for high-definition televisions and the push to make them larger. A popular gift in the past holiday season was the digital picture frame: as manufacturers sought to fill the supply, there was a shortage of under-10-inch screens. Executives in the display business contend that the growth in new classes of devices needing screens is making it harder for temporary shortages of certain screen sizes to sort themselves out.
